Re: New 383 Smoking...AAHH
There was a different poster with a similar problem and here was my reply...
What heads are you running? Lifter valley plugs by any chance? I chased this problem and have it about 95% solved (still get a little puff every now and then during braking).
Ultimately I think it was a combo of the lifter valley plug and screen kit plus the intake seal. Oil was pooling under the intake and during turns, etc. it would suck up into the bottom of the intake ports.
I went to better valve stem seals too but don't know if that was really the problem....
